Warning: SOME ARGUMENTS ARE DEPRECATED: (keep_dims). They will be removed in a future version.
Instructions for updating:
keep_dims is deprecated, use keepdims instead

Reduces input_tensor along the dimensions given in axis.
Unless keepdims is true, the rank of the tensor is reduced by 1 for each
entry in axis. If keepdims is true, the reduced dimensions
are retained with length 1.

If axis is None, all dimensions are reduced, and a
tensor with a single element is returned.

Args:

input_tensor: The tensor to reduce. Should have real numeric type.

axis: The dimensions to reduce. If None (the default), reduces all
dimensions. Must be in the range [-rank(input_tensor),
rank(input_tensor)).
